Abstract
The utility model relates to a simple whole cover type scavenger fan which belongs to a pumping device whose operating fluid is air. A complete whole plate is used as the front cover plate (1) of the scavenger fan, the cover plate (1) is hinged with the outer shell (3) of the scavenger fan, and the opening and the closing of the cover plate (1) are pushed by a push rod (2). The utility model combines the advantages of shutter type scavenger fans and scavenger fans without covers. The utility model is especially suitable for fume extractors.
Description
Simple and easy whole cover type ventilation fan.Belonging to working fluid is the pumping installations of air.
The axial flow ventilation fan that uses has two kinds of styles at present, and a kind of is louvre type, and another kind is a non-cover type.Promptly form the ventilation fan body by motor, flabellum, supporting frame and shell.Body protecgulum (one side that contacts with external environment) is the louvre type that is of venetian blind, only is the non-cover type that is of body.The louvre type airtight performance is better, but resistance is big, cleans the maintenance inconvenience.Non-cover type is simple in structure, and wind-force is big, but when off working state, seal is poor, especially winter, influenced greatly by the environment cold airflow, and then coming in and going out to mosquito in summer provides convenience.
The purpose of this utility model provides a kind of simple and easy whole cover type ventilation fan.During the work of this ventilation fan similar in appearance to the uncovered ventilation fan, during off working state, similar in appearance to the louvre type ventilation fan.
Solution of the present utility model is to make front shroud with a complete whole plate.Cover plate and shell are hinged, and can sway.Cover plate is provided with and promotes the push rod that cover plate rotates.Push rod penetrates shell and is connected with cover plate.
The utility model is owing to adopted whole plate to make front shroud, and cover plate opening and closing is convenient, has therefore had both louvre type, the advantage of non-cover type ventilation fan, and this ventilation fan is as range hood, and its advantage is more outstanding.
Accompanying drawing 1 is a structural representation of the present utility model.
Cover plate 1 and shell 3 hinges, push rod 2 is fixed on the cover plate 1, and its free end penetrates shell 3.Flabellum 4, motor 6 usefulness supporting frames 5 are fixed on the shell 3.
Embodiment 1: cover plate 1 is preferentially selected the mode of upwardly opening for use, and push rod 2 is preferentially selected the arc push rod for use, and push rod has ratchet, lives with cover plate 1 usefulness bearing pin and twists, and the free end of cover plate 1 is preferentially selected for use magnetic to bump with shell 3 contacting points and combined.This mode of execution is equally applicable to left and right opening ways.
Embodiment 2: cover plate 1 downward opening ways, and push rod 2 is an arc, no ratchet is fixed on the cover plate 1.
Embodiment 3: push rod 2 is the single folding formula of level, Vertical direction, and two sections push rods flexibly connect, and vertical section length equals distance between the cover plate after horizontal segment and the unlatching, and the horizontal segment push rod has ratchet.This mode of execution is adapted to upper and lower, left and right and opens and closes cover plate.
Claims (3)
1, simple and easy whole cover type ventilation fan is formed the ventilation fan body by motor, flabellum, supporting frame and shell, it is characterized in that cover plate (1) is a complete whole plate, and cover plate (1) connects with shell (3) strand, and push rod (2) penetrates shell (3) and is connected with cover plate (1).
2, simple and easy whole cover type ventilation fan according to claim 1 is characterized in that push rod (2) is an arc, and push rod has ratchet on (2).
3, simple and easy whole cover type ventilation fan according to claim 1 is characterized in that push rod (2) is the single folding formula of level, Vertical direction, and two sections push rods flexibly connect, and the horizontal segment push rod has ratchet.
